Microcellular networks
This chapter is concerned with microcells and the teletraffic that a microcellular network is able to support. A prerequisite is to discuss the numerous types of cells that are available to a network designer, and the role that microcells have, or may be expected to have, in high capacity mobile networks. We recall that a cell is an area surrounding a base station (BS) site where communications between mobile stations (MSs) and their BS are of an acceptable quality . The cell dimensions are different for an isolated cell compared to a cell in a cluster where the cochannel interference effectively decreases cell size. Cells are arranged in clusters, with clusters tessellated. The bandwidth allocated by the regulatory body (the Radio Communications Agency in the UK) is reused in every cluster in order to increase the number of radio channels that can be accommodated on the network. The bandwidth assigned to the cell sites within a cluster is in practice complex. For simplicity we will assume the division to be equal, unless otherwise stated.
